Lehle 3@1

Lehle about the SGoS version

The Lehle 3at1 SGoS permits stereo switching, via gold-plated relays, between up to 3 different instruments. The signal is routed without any loss from Inputs A B or C to Outputs 1 and 2, enabling you to switch easily between amp and tuner.

The Lehle 3at1 SGoS can be controlled and synchronized with other Lehle SGoS Switchers via MIDI.

Lehle (2003)

The Lehle 3@1 enables you to switch between a range of instruments in stereo via gold-plated relays. The signal is routed with no semiconductors and no corruption via Inputs A, B or C to the outputs.

outputThe stereo signal is routed directly via gold-plated relays to the two outputs. One output can, for instance, be connected to the amplifier and the other used for the tuner.

input signalThe stereo signal is routed directly via gold-plated relays optionally via Input A, B or C to the two outputs. Volume on Inputs B and C can be adjusted by means of trimpots. It is necessary to remove the housing cover using its four screws in order to set the potentiometers the first time. The potentiometers are located at the same level as their inputs.

input signalThe input signal from A is automatically routed to the two outputs if the Lehle 3@1 is not active.

power supplyThe Lehle 3@1 requires a power supply of between 8 and 20 V. Polarity is of no importance. The supply voltage is internally rectified and stabilized in order to guarantee trouble-free operation. A thermal cut-out automatically trips and switches the unit off if a short-circuit occurs. A correctly fitting plug connector for the power-supply socket of the Lehle 3@1 is supplied. This can be soldered to the required power unit if necessary.

Master-Slave with other switchersEach Lehle 3@1 can be easily retrofitted with a DIN socket in order to permit parallel operation with other Lehle switches in master/slave mode.

LEDs behind a magnifying lensThe high-intensity LEDs installed behind a magnifying lens make it easy to read the switching state (A, B or C) even under spotlights.

indestructible switching mechanismThe buttons which control State A, B or C are actuated inside the switch by means of a virtually indestructible switching mechanism.

solid box / easy to fixThe base of the Lehle 3@1 can be secured without difficulty. First remove the four housing screws for the cover, and then screw the base of the switch to a base-plate using the two screws supplied with the unit, the washers and the spacer elements.
